For green tea, the shelf life of Tongchu Hechang is about 1 year, while the storage time of black tea is relatively long, and the shelf life is about 2 years. If the above tea leaves have been left for 3 years and have exceeded the expiration date, it is not recommended to continue to make tea and drink it.

Types of Tea:

1.Green tea. Green tea is one of the main types of tea in China, which refers to the beverage made from the new leaves or buds of the tea tree, unfermented, through the process of killing, shaping, drying and so on.

The color of the finished product and the brewed tea soup retain the green style of fresh tea leaves, retain more natural substances in the fresh leaves, retain about 50% of chlorophyll, and lose less vitamins.

2.Green tea. Oolong tea, also known as green tea, has many varieties and is a tea category with distinctive Chinese characteristics among several major tea categories in China.

Oolong tea is a high-quality tea made after picking, withering, shaking, frying, rolling, and roasting. Oolong tea was derived from the Song Dynasty Gongcha Dragon Group and Phoenix Cake Evolution Hui Hu Pai, and was created around 1725 (during the Yongzheng period of the Qing Dynasty). After tasting, the teeth and cheeks are fragrant, and the aftertaste is sweet and fresh.

3.Yellow tea. Yellow tea is a specialty of China.

According to the size of fresh leaves, old and young buds, it is divided into yellow bud tea, yellow small tea and yellow big tea. Yellow bud tea mainly includes Junshan silver needle, Mengding yellow bud and Huoshan yellow bud, Yuan'an yellow tea; For example, Weishan Maojian, Pingyang Yellow Soup, Ya'an Yellow Tea, etc. are all yellow tea. After the impoundment of water in the Three Gorges Reservoir area, the perennial fog in the Zigui Mountains has been shrouded, forming a unique Zigui yellow tea, which also belongs to the yellow tea.

Although some people are hyping the concept of aged black tea now, it is basically a gimmick for storytelling and has no practical meaning. If the quality of black tea is left for too long, the quality will not be effectively improved, and it may even continue to decline.

The shelf life of white, black, and pu-erh teas varies depending on the specific storage conditions. In a good preservation environment, these three teas can be fully oxidized to become an aged tea of better quality. However, if the storage environment is poor, they will also become moldy and spoiled, and they can no longer be drunk.

Normally, the quality of white tea, black tea and Pu'er tea will reach a relatively high level if it is stored for more than 10 years, and the quality of most old teas will slowly decline to varying degrees after more than 20 years. In other words, even if the old tea can be stored for a long time, its life cycle will slowly decay after reaching its peak, and it is not necessarily better that the longer it is.
